Speaker wires and connectors corroded

Asked by Apr 14, 2017 at 09:08 AM about the 2014 Toyota Corolla S

Question type: Maintenance & Repair

I've been informed by my local dealership that the wires and connectors for my
front speakers are corroded. I've done nothing to make this happen. Toyota has
stated it will cost $600+ to fix. This is unacceptable to me as I've only had the
car for 2.5 years. They've now come back with an offer to split the cost, so I
would have to pay $210. Again, this seems ridiculous. Although I'm not an
expert, I believe there's an issue with the seals in and around the car doors.
How can I get Toyota to fix the speakers, wires and connectors for free? I'm
past the 60,000 km warranty.

this is currently happening to my 2015 corolla S. take the door panel off and check that the plastic covering that goes overtop of the electrical components is sealed (the black goop) all the way around. Thats what was letting water inside the door. If you need to reseal it use goop automotive adhesive, it works great. Goodluck


I found the same thing on my 2015 Corolla S today. Wires and speaker plugs coroded took the opportunity to replace the speakers as I was already taking the door panels off to repair the connections. Pretty easy job to do yourself if your handy. The connections on the factory speakers can be run straight with speaker wire if you have a soldering iron.
